Billie Eilish and Charli XCX Perform Surprise 'Guess' Remix at L.A. Show

The Grammy-nominated duo energized the Kia Forum with their first live performance of the remix, marking a highlight of Eilish's North American tour.

Billie Eilish invited Charli XCX onstage at the Kia Forum in Los Angeles for a surprise performance of their 'Guess' remix during Eilish's ongoing North American tour.
The performance featured vibrant green lighting and lasers, a signature aesthetic tied to Charli XCX's remix album, 'Brat and It’s Completely Different but Also Still Brat.'
The collaborative remix 'Guess' is nominated for Best Pop Duo/Group Performance at the 2025 Grammy Awards, with both artists competing in multiple major categories.
Eilish's 'Hit Me Hard and Soft' album and Charli XCX's 'Brat' have both received critical acclaim, with 'Brat' named NME's Album of the Year.
Eilish has two more sold-out shows at the Kia Forum this week before continuing her tour internationally, while Charli XCX is preparing for her own headline arena tour in 2025.
